Maltose, Trehalose and Cellobiose are all formed solely from glucose molecules.
Less common disaccharides of glucose include:
Kojibiose, Nigerose, Isomaltose, β,β-Trehalose, α,β-Trehalose, Sophorose, Laminaribiose and Gentiobiose.
When you link two glucose molecules together you are going through dehydration synthesis which is getting rid of the water in the molecules and by doing that you have water, H2O, as the by-product.

Two monosaccharides are needed to form one maltose molecule. Specifically, maltose is comprised of two glucose molecules joined together through a condensation reaction, which releases a molecule of water.
Two ATP molecules are needed to activate glucose during the initial steps of glycolysis, where glucose is converted to glucose-6-phosphate. This process requires the input of energy in the form of ATP to initiate the breakdown of glucose.
The 3-carbon molecule produced when glucose is broken in half in glycolysis is pyruvic acid. It gives energy to living cells through the Krebs cycle.
Maltose
Sucrose is formed by glucose and fructose.
One molecule of glucose can produce 2 molecules of radioactive alcohol through the process of fermentation, where glucose is converted into ethanol and carbon dioxide by yeast.
Each glucose molecule produces 2 pyruvate molecules so 3 glucose will make 3*2=6 pyruvate molecules.
Two alpha glucose molecules would be two individual units of the monosaccharide glucose connected through alpha glycosidic bonds. Alpha glucose is a specific form of glucose where the hydroxyl group on the first carbon is in a downward position. When two alpha glucose molecules bond together, they form a disaccharide known as maltose.
When you link two glucose molecules together you are going through dehydration synthesis which is getting rid of the water in the molecules and by doing that you have water, H2O, as the by-product.

In glycolysis two net molecules of ATP are formed. Four ATP are formed but two are required in the initial activation of glucose.
It takes 2 monosaccharide molecules to form a maltose molecule. Those are 2 glucose molecules. So 2 glucose molecules join together to make 1 maltose molecule.
If 2 NADH molecules were produced in glycolysis, it means that 1 glucose molecule was broken down. Each glucose molecule yields 2 NADH molecules during glycolysis.
In glycolysis, one glucose molecule produces a net yield of two ATP molecules at the end of the process.
Two water molecules are formed by a total of 6 atoms: 2 from each oxygen atom and 1 from each hydrogen atom.
